Just wanted to share my experience with the Di-marzio tech support. I've got an old 1991 RG570 that I have had in pieces for over two years (still my pride and joy getting a new paint job)and have finally bought a new middle pick up to compliment the bridge and neck ones from an upgrade in 92 (Super Distortion / Fast Track / PAF PRO) Anyway with the PAF PRO and FT being able to be tapped I thought I would make the most of the 5 way and and a new PP tone pot. Had me buggered how to wire it up and searched the net for weeks. Finally spat it and saw a link to Di-marzio tech advice. Got in contact with these guys and within 2 days they sent me custom wiring diagrams for different options. I was floored with how willingly they assisted me. These guys rock.
